Have the others done any videos?

General Two Stroke Talk / Courtney Duncan WMX at Hangtown Qualifies 1st on a YZ 125

Another guy you guys might have heard of is Darryl King. 2nd in world championships many moons ago, World Vet Champion last year, multi time New Zealand and Australian MX champion. He has won the New Zealand MX2 championships the last couple of years on a , wait for it, 2 stroke YZ250, against all the 4 strokes. He won in 2011 and 2010. He is still seriously quick despite being a Vet rider and has raced in the MX2 class for the last few years. He is finally is retiring this year and was in the top 3 of all the races in this years 2013 New Zealand MX2 class and may have won but for an injury half way through the series. Just for some added spice a number of Australian MX2 champions also come over to race the NZ championships. Great to see Kingy beating them all on his trusty YZ250 zinger. Another 2 stroker who came over to the NZ championships and did well and who is currently running 3rd in the 2013 Australian MX2 championships as we speak is Brock Winston riding a KTM250 zinger. So maybe all is not lost.  They can be competitive

Many riders in NZ often put 2 strokes into 4 stroke frames and do well with them. In fact there has been testing on a electronic fuel injected 2 stroke 500cc and has been doing well. Take a look at this. A CR500 2 stroke fuel injected in a YZF450 frame. Shows drags with 450 4 strokes. Ridden by a mutli champion MX rider. Designed and built in New Zealand. 105kgs wet, rider says rides like a 250 zinger.




Re Josh Coppins. Raced MX world championship GPs in Europe for 16 years, twice 2nd in MX1 world championships, only rider to beat Stefan Everts on a number of occasions, 2 times 3rd in MX of Nations including once being part of the team coming 3rd  in the USA.  Coppins took over Everts ride and Minaldi Yamaha and in 2006 or 2007 Coppins was so far in the lead in the MX1 he would have won the series in one more race but a stone jammed his rear brakes and threw  him into a fence and injured him putting him out of the championships. A very cruel blow considering he  had won some 6 GPs by mid season.  Coppins is also the current Australian MX1 champion and is a multi time British MX1 champion. He just retired this year and now runs the Yamaha team in NZ and is a test rider for the Yamaha factory team in Australia.

I think Coppins would have quite abit of insight into whether Courtney would qualify for a Pro mens race. I would agree with him for the reasons set out in the earlier posting. Saw an interveiew back here in NZ with Courtney Duncan the other day and she confirmed she will be racing the rest of the series in the USA and then do Lorreta Lynns and then see what happens from there.

 Racer X

I wouldn't rule our Courtney Duncan never qualifying for a Mens Pro race.  Here is some facts you may not know.

We all said the same thing in New Zealand when she started racing the guys but she proved us very very wrong. Not only did she qualify for her very first senior race against men in the (February) 2013 New Zealand championships 125cc class (we are lucky enough to have a 125cc championship as well as the 250 and 450), she went on to win the round, convincingly, against the men. The rougher the track got the faster she went. She was the only girl at the championship.

Her laps times that day would have also qualified her for the New Zealand championships 250cc Pro and the 450cc Pro open. Ben Townley raced and many Australian champion riders also came over to race that meeting.

Of worthy note: She also got 6th overall (including a 3rd in one race) in the World FIM Junior Championships in the 13 -16 85cc class against all the boys. She was the only female rider at the event. This was in the junior world FIM championships, the same one Eli Tomac won that year.

Now I am not saying that means a lot in the USA where the pro riders are all seriously fast, so I will give a little more info....

In Hangtown she was riding a 125 with a near stock 125 engine (it was not a 144) , as I understand she just had a pipe and some reeds. It was her very first ever Pro Race in the USA. She had never been to that track before. She has only been riding the 125cc this year. She just turned 17. She has no factory support and she had a friend from New Zealand spannering for her. They drove across the USA in a small RV. Her 1st qualifying time was 2.13. She won the 1st race by 29 seconds and the 2nd by 14 seconds.  It seems too on the day, I was there, that she had more in the tank as well. Makes the feat all the more incredible when you start adding it all up.

Give her a few more years racing, a factory supported bike, with some more experience in the USA  and I think she may well qualify, in fact I know she will.

Remember a lot us said the exact same thing and we had to swallow our words when she cleaned up against the best riders in New Zealand in the 2013 New Zealand 125cc championship round back in February where she was the only girl racing. (and she had only just started racing the 125cc and had only just come back from a year off due to injury). A lot of senior pro racers (125cc class) where left shaking their head that day........

She also came 3rd behind Cooper Webb last year in the 85/150cc class in USA as well and Cooper Webb was around top 10 at Hangtown wasnt he

Food for thought 

How about a friendly wager??
